They have great support too. Initially when I had the RCB issues, I contacted them, and they sent me a loaner and asked me to send in mine for testing. They found no problem, so I got mine back and returned the loaner. All at no cost, and I live in Sweden.
Much better than the local car dealer who handled it very poorly. Yet the problem was in the car, because after an ICCU update a month ago all problems went away.
Is this in W? kW? what does grid_power look like and inverter_power?
i cant seem to figure it out 
(read up in the text and it seems to be in W? testing this, lets see :o
Yes, the unit you use is W
I just recently acquired Go-e Charger and implemented this automation. Took me awhile to get it working tough, because first I couldn’t get it to publish grid and PV power into right topic. For some reason when I copied the script it dropped the parentheses around the topic. So, didn’t work until I figured that out. Secondly you need to be able to put the charger into “ECO” mode from HA. This also took me awhile to figure out.
Now that it’s working I think it’s even better that building my own automation around that. Go-e is very dynamically adjusting the amps and phases according to grid power. It tries to balance the PV output and total consumption so, that they are evened out and the total is near zero. Go-e is also reacting sudden PV output drop rapidly and will pause charging accordingly. So, works very well!
Yes, the built-in automation in the charger works very well.
So far I do not have much automated around the go-echarger in HA. I mainly send the PV data to it, and then I use their app to control if it should be in ECO mode or not, and which hours per day that it should allow charging. The charger itself handles all the rest with ease. And now that Hyundai has finally fixed the ICCU in my car so that it no longer trips the RCB I can even put it in automatic phase mode without worrying that it would stop charging the next time it goes from 3 to 1-phase.
I followed your discussion with high interest, because I use a go e-charger and measure the current of the grid with shelly 3EM (in/output). Both devices are integrated in my HA and working well.
I’m missing a second power converter to measure the current of the PV itself and my question is, do I need to measure directly the PV? Because, I could assume a constant power consumption of (app 400W) and calculate the PV power = pgrid - 400W. The only disadvantage is that this method is not optimized to zero external power.
Thx for your Code.
I have setup the automation and see the data on the app that i write.
But the charger did not start.
In the App under API Views i can see the Data.
In the App stand that for pv the controller is nessesary.
Status Said: “ECO Modul Ladepause”
Is there another option i can set?
aWattar Mode was working
Let’s make some parts clear because I’m sure some people will get confused.
At soon you send pgrid - 5000w to the charger the charger will charge with 4.2KW more or less if you got another device ask for power and the pgrid drop the charger also drops.
You must remember that the drop of the charging power some times is with delay because of the CAR inverter and not because of the charger.
I got this setup and runs perfect and yes is optimized for zero external power.
If you check in here around post# 110 you will see that the only part is THE WORKING part is the pgrid for the charger.
My go-Charger just reads the Mqtt messages once after being reloaded.
The broker is running and i can see the messages appear from the charger.
Any advice on that issue?
During installation of mosquitto, mosquitto integration and go-echarger integration, I tested both topic versions - “go-eCharger/xxxxxx” and “/go-eCharger/xxxxxx”.
go-eCharger integration searches for both topics during setup and in my case it took the one, that I did not use anymore and therefore did not get new messages, which came on the other topic version.
After cleaning the mosquitto db from old topics, go-eCharger integration works fine.
In case you are looking for some energy management system (PV surplus charging,…) for your go-e then take a look here: GitHub - gsaurer/ha-ems: Energy managemnt system for Home Assistant
I have put together some blueprints to achieve an automated charging experience.
Before the latest firmware upgrade I could balance the net in/out from the grid to 0 quite nicely by sending the solar and grid values to ids, but now with the power preference and grid target settings I can’t get this to work anymore. There is a lot of import or export whatever settings I try. Anyone else have this problem?
It depends. 
Which issues are you trying to solve?
Hi syssi…sorry for the delay…
Somehow I let the 56.8 before my hollidays :
Was not charging with more than 4 kw
Was not communicate correct with Home assistant
The app was getting crazy values
I just arrive home and all is working correct. I will keep an eye on it and I report back.
I found one bug/issue.
The flexible energy tariff and the PV surplus must both be configured on the app, if not you can’t change the charge mode from the App from normal to ECO…but from home assistant you can change it . That was my issue but I found it after a few hours of searching what is wrong
